摘　　要：本文从稀土元素在植物中的含量分布、存在形式、细胞定位以及它对植物种子萌发、根系发育、植物生长、养分吸收、内源激素变化、光合作用。This paper depicts the physiological basis for the application of rare earth elements in agriculture. The contents, distribution, the forms and cytolocalization of rare earth elements in plants are discussed. The effects of rare earth elements on seed germination, root development, seedling growth, nutrient uptake, change of hormones, and photosynthesis are also discussed. Further more the rare earth elements affecting the plasma membrane and calcium physiological function are reviewed as well.
